Koenigsegg is celebrating its 20th anniversary in a mega way. The Swedish supercar maker has revealed more details about the Koenigsegg Agera One:1. The world’s first “megacar” gets its name from its 1 metric horsepower per 1 kilogram power-to-weight ratio, and creates a new supercar sub-genre as the first production car to make 1 megawatt of power.

The 1340 kilogram (2954 pound) Koenigsegg Agera One:1 produces 1340 metric horsepower or 1321 hp US hp. That’s 187hp more than the current Agera R, and 137hp more than the much heavier Bugatti Veyron Super Sport. While Koenigsegg hasn’t revealed all the updates to the megacar’s twin-turbo 5.0-liter V-8, we know the new Agera One:1 features 3D-printed variable turbo housings for improved response and low-end torque, as well as a 3D printed titanium exhaust end piece that saves 14 ounces of weight. Another weight saving measure includes a 20-percent lighter carbon fiber chassis made with new high modulus fibers.

Koenigsegg has also paid close attention to the Agera One:1’s handling dynamics with variable ride height, as well as adjustable shock absorbers and spring ratio stiffness. Active aerodynamics includes independent left and right flaps under the front splitter and a hydraulically actuated dual plane rear wing mounted to the top. Koenigsegg says the Agera One:1 is capable of 2.0 g in lateral acceleration on street-legal cup tires, and that the active aerodynamics provide 1344 pounds of downforce at 160mph.

Inside, the Agera One:1 sports vented carbon fiber racing seats with memory foam padding, 3G internet connectivity for telemetry, performance, lap times, and software upgrades, as well as its own iPhone app. The 3G connection and GPS are also used for a Predictive Active Chassis and Aero Track Mode. An active noise cancelling seat option is also available.

Koenigsegg will reveal more details at the Koenigsegg Agera One:1 debut at the 2014 Geneva Motor Show next week. Unfortunately for us, all the megacar's specs are good for bench racing -- Koenigsegg says every planned production vehicle has been sold.
